DD currently uses tampons, but wants to convert to a menstrual cup. She has very heavy periods (soaks through a super plus tampon and onto a pad in 1 hour, or less). Which brand is best at not leaking as she suffers from this, and also easy to use? Stupid question but do I get the pre-birth size as obviously she hasn’t had a baby, but I’m worried the normal one won’t absorb her flow? Thanks
